IMPROVEMENT IN GLASS DECORATIONS.

Speciiication forming part of Letters Patent No. 129,8565 dated July 23, 1872;

To all whom 'it may concern: a

Be it known that I, WILLIAM NIELsoN, of the city, county, and State of New York, have invented a new and useful Improvement in the Manufacture of Glass Decorations; and I do hereby declare the following to be a full, clear, and exact description thereof, which Will enable those skilled in the art to make and use the same, reference being had to the accompanyingdrawing forming part of this specication,-in which drawing- `Figure l represents a transverse section of my invention.` Fig. 2 is an inverted plan of the same. y

Similar letters indicate corresponding parts. This invention consists in a glass decoration produced by first applying to the' back of `a pane of glass a suitable design in oil-paint,

then spreadin g over the paint, before the same is dry, av layer of sawdust, and over the sawdust a layer of plaster of Paris, in such mannerthat an article is obtained which can be readily attachedto a Wall, and which, when attached, preserves its beauty for a long time. In thedrawllg, the letter A designates a paneof glass, which is provided with any dea sired `designproducedby applying oil-paint to itsback. Before this oilipaint is dry I I spread over it a layer of sawdust, and as the paint dries the sawdust is firmly retained; or, if desired,the paint used for the design may be left to dry and an additional layer of paint may be applied to retain the sawdust. After the paint has dried I moisten the sawdust and spread over it a layer of plaster of Paris, the sawdust forming the means for uniting the After the plaster of Paris has dried my decoration is ready for the. market; and if it is to be applied lto a wall it is only necessary to spread over the back layer of plaster of Paris an additional coat of plaster of Paris and press this up against the` wall, retaining it in position until the plaster of Paris has set.

What I claim as new, and desire to secure by Letters Patent, is

A glass decoration produced by applying to its back a suitable design in oil-paint, then spreading thereon a layer of `sawdust, and on the sawdust a layer of plaster of Paris, substantially in the manner herein set forth.

` W. NIELSON.
